Question My 1990 Ranger 2.9, stalls at stops.



my 1990 ford ranger starts up just fine before work, i can pull out with no problems, but after three stop signs, at the fourth stop it a light, the engine lurches* up and stalls out, then 1/2 mile later at the next light, it will lurch and stall again. then it is on to the bosses house just fine....
afterwork, it starts up just fine, idles for about 5 minutes, and once i put it in drive and begin to take off, it just stalls. it usually lurches at the first stop lights, when i have to slow down or after i've stopped at the light and try to accelerate. everytime it stalls, it always starts right back up. i live 1 1/2 miles from work. it happens before and after work, or after long periods of sitting. i came home from work today, after having the usual problems that i stated before, but an hour later, i drove it to my mothers house, aprox. 4 miles away, and didn't have the problem. can i get a list of possible problems and solutions? i'm a begginer.


*lurch- it jumps erradically (rpm800-2200) vroom2200, chug1200 vroom2200, chug1000 vroom2200 chug800 vroom2200 stall000
